no
longer
covered
by
the
directives
in
force
in
the
area
of
pressure

of
the
unit,
it
is
highly
recommended
to
avoid
any
sudden
or
violent
motion
in
order
to
protect
the
inner
components
and
the
frame.
The
units
can
be
lifted
by

of
a
forklift
or,
otherwise
by
mean
of
belts,
making

to
damage
the
lateral
panels
and
the
cover
of
the
unit
using
a
structure
of
spacers
as
shown
in
the
drawing.
In
this
context,
it
is
necessary
to
hook
indirectly
the
unit
to
the
basement
but
on
two
steel
pipes
of
adequate
dimension
that
to
pass
into
the

7.3
LOCATION
AND
MINIMUM
TECHNICAL
CLEARANCES
All
the
N
‐
i
‐
HP
models
are
designed
for
outdoor
installations;
any
cover
over
the
unit
or
locating
near
trees
(even
if
they
partially
cover
the
unit)
has
to
be
avoided
in
order
to
allow
the
air
recirculation.
It
is
advisable
to
realize
a
supporing
basement,
with
adeguate
size
similar
to
unit
foot
‐
print.
The
unit
vibration
level
is
very
low:
it
is
advisable
however,
to
fit
a
rigid
rubber
band
between
basement
and
unit
base
‐
frame.
It
is
also
possible
to
install
anti
‐
vibration
supports
(springs
or
rubbers)
to
keep
vibrations
at
a
very
low
level.
An
absolute
care
has
to
be
taken
to
ensure
adequate
air
volume
to
the
condenser.
The
re
‐
circulation
of
discharge
air
has
to
be
avoided;
failure
to
observe
this
point
will
result
in
poor
performance
or
activation
of
safety
controls.
For
these
reasons
it
is
necessary
to
observe
the
following
clearances:
